TitleCard

Composable Component

Opinionated Wear Material Card that offers a specific 3 slot layout to show interactive information about an application, e.g. a message. TitleCards are designed for use within an application.

Android
@Composable
public fun TitleCard(
    onClick: () -> Unit,
    title: @Composable RowScope.() -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    time: @Composable (RowScope.() -> Unit)? = null,
    backgroundPainter: Painter = CardDefaults.cardBackgroundPainter(),
    contentColor: Color = MaterialTheme.colors.onSurfaceVariant,
    titleColor: Color = MaterialTheme.colors.onSurface,
    timeColor: Color = contentColor,
    content: @Composable ColumnScope.() -> Unit,
)

Parameters

onClickWill be called when the user clicks the card
titleA slot for displaying the title of the card, expected to be one or two lines of text of Typography.button
modifierModifier to be applied to the card
enabledControls the enabled state of the card. When false, this card will not be clickable and there will be no ripple effect on click. Wear cards do not have any specific elevation or alpha differences when not enabled - they are simply not clickable.
timeAn optional slot for displaying the time relevant to the contents of the card, expected to be a short piece of end aligned text.
backgroundPainterA painter used to paint the background of the card. A title card can have either a gradient background or an image background, use CardDefaults.cardBackgroundPainter() or CardDefaults.imageBackgroundPainter() to obtain an appropriate painter
contentColorThe default color to use for content() slot unless explicitly set.
titleColorThe default color to use for title() slot unless explicitly set.
timeColorThe default color to use for time() slot unless explicitly set.
contentSlot for composable body content displayed on the Card
